-Capacitors are essentially very large gates. ​ Say for example that one wants a capacitor to ground. ​ In a metal gate CMOS process this can be done by simply creating a well and putting a large M1 over the well.  For example, if one wants a capacitor to ground, you could create a large P well and then put metal on top.  The P well is connected to ground and M1 to the desired connection. ​ Example metal gate CMOS capacitor:+Capacitors are essentially very large gates. ​ Say for example that one wants a capacitor to ground. ​ In a metal gate CMOS process this can be done by simply creating a well and putting a large M1 over the well.  For example, if one wants a capacitor to ground, you could create a large P well and then put metal on top.  The P well is connected to ground and M1 to the desired connection. ​ Example metal gate CMOS capacitor ​(ST 24C02):
